The Megatherium is an extinct giant ground sloth, that inhabited South America. This Pliocene era sloth weighed as much as four tons, that’s the equivalent of today’s elephant, and was four meters tall. These majestic giant mammals disappeared around 10,000 years ago, about the same time as the end of the last ice age. Their remains show up as recently as the rise of mankind, making man the most possible culprit for the Megatherium’s extinction.
